Definitions

  • This invention is in the field of thin-walled flexible packaging, customarily referred to as “pouches , " and particularly in the field of pouches fitted with a spout for dispensing the product , customarily referred to as “spouted pouches . "
  • the closures must have a tamper evident seal that makes it clear to the user i f the package has already been opened, especially in the case of food products , for which correct preservation is essential , without , of course , compromising the convenience of use .

  • the grip surface 14 comprising a bead 16 extends from a first zone 18' of the outer surface of the cap wall 4 to a second zone 18' ’ of the cap wall 4, diametrically opposed to the first zone 18' .
  • the grip surface 14 further comprises a partition 20 , contained between two flat , parallel faces , extending between the bead 16 , the cap wall 4 , and the cap base 10 .
  • the partition 20 is lower with respect to the bead 16 .
  • the closure 1 further comprises a tamper evident seal 30 suitable for indicating the first opening of the closure .
  • the tamper evident seal 30 comprises a tamper evident ring 32 suitable for being attached to the spout , whereby it is connected thereto at least axially, and, for example , free to rotate thereon .
  • the tamper evident ring 32 comprises an annular wal l 34 having a lower face 34a, e . g . , in the form of a circular crown lying in an imaginary plane orthogonal to the cap axis Y, a cylindrical outer side surface 34b, an inner side surface 34c, and an upper annular face 34d, which delimits the annular wall 34 at the top .

  • the configuration of the tamper evident seal ensures a high level of comfort in the use of the flexible packaging because , when the bridges break as a result of unscrewing the cap, the residual sections that remain connected to the tamper evident ring are entirely contained in the valleys of the tamper evident ring and therefore cannot get in the way of or bother users who use the spout by holding it between their lips .
  • the closure comprises a strap 60 suitable for keeping the cap 2 connected to the tamper evident ring 32 even when the tamper evident seal is broken .
  • the strap is permanently connected, unless it is torn of f forcibly by pulling .

  • a median imaginary plane is defined with respect to the thickness , on which the cap axis Y lies ; preferably, the median imaginary plane of the strap 60 coincides with the median imaginary plane of the grip surface 14 .
  • the closure is preferably made in a single piece of plastics material , for example by inj ection molding .
  • the closure according to this invention satis fies the aforementioned requirements , in that it provides a tamper evident seal that does not interfere with a comfortable use of the spout .

Abstract

La présente invention concerne une fermeture (1) pour un bec verseur d'un emballage souple à paroi mince comprenant un capuchon (2) et un joint d'inviolabilité (30) comprenant une bague d'inviolabilité (32) conçue pour être fixée au bec verseur, une partie d'inviolabilité (40) solidaire du capuchon (2), et au moins un pont de rupture (50) qui, lorsque le joint est ininterrompu, relie la bague d'inviolabilité (32) à la partie d'inviolabilité (40). La bague d'inviolabilité (32) présente une face supérieure (34d) la délimitant sur le dessus, constituée d'une surface ondulée comportant des arêtes (36) et des creux (38) circonférentiellement successifs, chaque creux (38) présentant une surface inférieure (38'). La partie d'inviolabilité (40) comprend au moins une dent d'inviolabilité (42) ayant une face supérieure (42a). Ladite face supérieure (42a) est contenue dans un creux respectif (38), et ledit ou lesdits ponts (50) relient la surface inférieure (38') et ladite face supérieure (42a) et sont contenus dans ledit creux (38).
